it's a great game, although there's some glitches and the soldiers could have been just a little smarter ( or at least enough not to kill each other) 4/5
Strategy Guide: PLEASE REPOST!! --Start with one guy..I recommend the Bloody. As you win battles you level to 30. During, you get NEW CARDS which is SOLELY BASED on WHAT LEVEL you get and WHICH DUDE you are playing! (Ex: Viecraft the Red unlocks Succubus, Dragon Rider, and Phoenix Strike) After you win a campaign, do a New Game++ and pick a DIFFERENT DUDE. Repeat game, keeping ALL cards you already won! As your NEW hero levels up, you get MORE CARDS. Repeat this process until you have BEATEN THE GAME with ALL HEROES. MAKE sure to UPGRADE and use all gold before you win each map or its lost! You can challenge Cave to get some easy cash, even though you lose. Now, you have ALL the cards except titans. For CAVES, repeat game with one of the 6 heroes. The catch is that EACH HERO has DIFFERENT STATS! Some have tough castles but crappy maximum mana, and vice versa. Upgrade all the cards that you want to use! Then, you can fight the Caves prepared to do so
